Native .Net 2.0 UDDI assembly

Hello, I'm trying to interact with a UDDI registry and I have several questions:

1. Does anybody know where I can find a UDDI assembly for .Net 2.0 The only reference I've found is for Microsoft.UDDI but it seems to be pretty old.

2. If that old DLL is the only option, do you know where I can get it, all the links redirect to the Windows SDK and it's a huge install, I just need the UDDI piece and is not clear which component of the SDK I need to install to get it.

3. As far as a know, MS is UDDI 2.0 is there a UDDi 3.0 for the assembly

Thanks in advance.
